So there I was having a great day and I shut off the boat to bring in a friend. I go to start it up and the engine cranks and cranks and never starts. I look and the fuel gauge reads empty but I just filled it up 10 min ago so that can't be. I end up getting towed in thinking the fuel pump is bad. I start troubleshooting and the fuel pump will operate when I wire it directly to the battery. Plus I tried to measure voltage on the supply side as the engine was being cranked and I saw no voltage from the supply side. Anyone ever experienced anything like this the fuel pump and fuel gauge do not work.

If you've lost both the pump and the fuel sender, I'd look at a bad ground at the fuel tank. Jumper it to the battery and see if the fuel level comes back. You could lose one as a fluke but to lose both, I'd look at common wires first.

You guys are the best!!!! It was the kill switch. The thing was still attached but I jiggled it a bit and then tried to start it and it started right up. I totally forgot about the thing and I would have thought it would have killed the whole system like a jet ski not just the fuel system.
